Patented Jan. 18, 1921.

To all whom it mayconcern Be it known that we, LoUIs E. WILLIAMS, Sr., and FRANK A. ADAMSKI, citizens of the United States, residing at Fremont, 1n the county of Sandusky and State of Ohio, have invented a certain new and useful Improvement in Apparatus for Pasting Dry-Cell Linings, of which the following is a full, clear, and exact description.

This invention relates to a method of and apparatus for applying flour paste to the lining of a dry cell. n the manufacture of dry cells of a well known type, a layer of paste made from flour and water is applied to a bibulous paper lining by means of a brush for instance. The pasted lining is placed in the zinc can either 1n a wet condition or after drying, and the mix is then tamped in'the cell.

The paste applied in the above manner is streaked, and not uniform over the entire surface. When a lining pasted in this way is used in a cell it is found upon examination of the zinc container after several months, that its "surface shows irregular corrosion corresponding to the irregularities of the paste. i

To eliminate the disadvantages referred to, we have devised and illustrated apparatus for uniformly applying the flour paste to the linings.

Referring to the drawings Figure 1 is a plan view of the apparatus with a considerable length of the central portions of the arrangement broken away.

Fig.2 is a front view having the same portions omitted as in Fig. 1.

Fig. 3 is an enlarged cross section of the lining feed end taken on the line A--A of Fig 1.

ig. 4 is a detail view of a part of the slide for feeding the linings.

Fig. 5- is an end view taken from the right of Fig. 1.

Fig. 6 is a sectional view on the line B-B of Fig. 2.

Fig. 7 is a sectional detail view of the spraying nozzle.

The supporting arrangement consists of a suitable framework made up for example, of longitudinal members 1, 2 joined by cross pieces 3 and carried by supporting legs 4 placed at suitable distances along the longibearings 11 adapted to be adjusted in slotted guides 12 by means of adjusting screws 13.

The driving means which operates the va- I1011S parts in a manner to be set forth hereafter, consists of a motor 14 that rotates a drive shaft 15 and pulley 15 through a belt 16. The bearings 17 for shaft 15 are fastened in a suitable manner to legs 4 (Fig. 2) and to one of a pair of supporting legs 18 extending above the longitudinal members 1, 2 for a purpose to be described later. A bevel gear 19 on shaft 15 meshes with bevel gear 20 on one end of a shaft 21 carried in standards 22, 23. The rotation of shaft 21 turns a pinion 24 thereon and drives a gear 25 through an intermediate idler 26. The idler is mounted between the prongs 27, 27 of a fork 28 and rotates on an axis 29. Shaft 21 passes through openings in the ends of the prongs and the other end of the fork 28, together with the idler 26, may be turned around the shaft 21 to enable the idler to be thrown in or out of mesh with gear 25 while maintaining it always in engagement with gear 24. For this purpose a lever 28' is fitted on one end of a shaft 29' having bearings 29" attached to the under side of the horizontal members. At the other end of the shaft is placed a crank 30 having a pin 31 engaging an opening in the end of the fork.

The throw of the lever 28' is limited by means of pins 32, 32', and a weight 33 is affixed to the lever to maintain it adjacent either pin.

Gear 25 rotates on a shaft 34, one bearing of which is arranged on the horizontal member 1, while the other is in the upper end of standard 23. A crank arm 35 is keyed on the end of shaft 34 and fastened to a slide 36 by means of a connecting rod 37 and pins 38 and 39. The guideway for the slide consists of a lower plate 40, side members 41, a top member 42 and in addition the slide has projecting ridges 43 which move in corresponding slots in the sides. The feeding end of the slide has a depression 44 of a depth corresponding with the thickness of the linings.

. The linings are fed by the slide from a stack 45 and are alined in proper position over the slide by two angle irons 46 and two flaring guides such as the s lit irons 47.

The linings are fed by the side between a pair of rolls 48, 49, rotated in opposite directions by a drivin mechanism consisting of a toothed whee 50 on shaft 34 and a toothed wheel 51 on axis 52 of roll 49 and a chain 53 in engagement with the toothed Wheels 50 and 51. The second roll 48 is driven from the first by means of a gear 54 on shaft 55 meshing with a gear '56 on'axis 52.

The means for moving the conveyer con- .sists for instance, of a spiral gear 57 on the drive shaft 15, meshing with a gear 58 o'nthe shaft 10. A small roller 59 is placed vertically over pulley 8, and has protruding ends slidable in guides 60 attached to the horizontal members.

The paste sprayer as shown in Fig. 7 consists of two spaced casings 61, 62 each tapering at the outlets 63, 64. The two are maintained in a spaced relation by any suitable means such as the perforated ring 65: A tube 66 passing feeds paste into the inner casing and a second tube 67 feeds air into the outer casing. The direction of the spray is inclined to the horizontal so that the overlapped portions are not subjected to the force of the sprayer whichwould tend to move or blow the linings out of position and expose the overlapped portion to the spray. The sprayer is moved from side to side to spread the spray evenly over the entire lining. The spray oscillatin mechanism consists of a double bell cran member 68 which is turned through a'certain angle around an axis 69 by means of the rotating crank 70, connectin rod 71 and pins 72 and 73. The bell crani has two oppositely projecting arms 764, 75 whilch are connected with pair 0 opposite pro'ectin arms 6, 7 on the tube 66. The aims 7%, 76 are connected by a cord 78 and arms 75, 77 are similarly connected by a cord 79. Bearings for the tube consist of a support 80 fastened between uprights 81 and a swinging bearing 82 suspended from an axis 83 attached to the uprights 18. A flexible hose 84 is attached to the end of the tube 66 to feed paste thereto.

Upon the horizontal members 1, 2 are placed a number of sections of hoods 85, 86, 87 which have projecting fianges88 secured to an angle iron 89. A suitable opening 90 1s provided in hood 85 for the sprayer and the end adjacent the hnlng feed is closed by hrough both casings in rotation.

an end member having an o )ening adapted to allow the passage of plan or support 5, belt 6 and the linings. he 0 osite end of hood. 76 issimilarly closed. 0 completely incase the conveyer, plates 91 may be fastened to the under side of the longitudinal su rts.

e paste not deposited on the lining will be removed by means of the drain box 92 and pipe 93 to the tank 94 arranged as shown in Figs. 1, 2 and 6.

Although for purposes of illustration we have shown only a relatively short section of hoodsfit will be understood that the section broken away is of sufficient length to permit the linings to be dried. This will be facilitated by forcing air taken in by a fan 95 through an air heater 96 and then through a pipe 97 into the conveyer casing. The air will then be removed by means of a pipe 98 and fan 99 located at the other end of the casing. The linings move in a direction opposite to the direction of the air current.

After being dried, the linings through the end of the casin down strips 101 into a receptacfie belt passes over the end pulley 7.

To place the apparatus in operation, the air heater 9 6 and fans 95, 99, will be started, thus drawing air from heater through the conveyer casing to fan 99. A stack of linings 45 will be placed between the wideways 46, 47 and the motor 14 started? By throwing lever 28' to the position shown in F ig. 2 the lining feed will be driven from the main shaft 15 through bevel gears 19, thus lacing shaft 21 and gear 25 The movement of the lever 28 turns shaft 29 and pin 31 through a certain angle and raises the fork 28 and idler 26 into engagement with the large gear 25, which operates the lining feed. shaft 34. Each rotation of this shaft will operate the 'slide 36 to remove one lining from the base of the pile and will move it far enough forward to cause it to be engaged by the rollers 48, 49. The rollers are driven from the same shaft as the lining feed mechanism through toothed wheels 50, 51, chain 53 and gears 54, 56. The linings are carried by the rollers to a 'point where they will be received between the belt conveyer 6 and the roller 59. The movement of the conveyer is produced through the spiral gear drive consisting of spiral 57 and gear 58 on the shaft 10 of pulley 8. The roll 59 is rotated by frictional engagement with the linings on the conveyer belt. In' the present case it is not necessary to apply paste to one edge of the ass and side as the 'lining because when the jacket is coiled in inthe manner already described.

the-arms 74, 75 through a certain angle,

and this movement will in turn be transmitted to arms 76, 77 through the connecting cords 7 8, 79. The excess paste will be withdrawn through the drain 9.2 to tank 94;. After passing the sprayer the linings are dried by the heated air current t is not essential in the operation of the apparatus to use either of the fans, if the belt con veyer is long enough, as the linings could then be dried in the open air,

When the linings pass over the pulley? they slide down the inclined strips 101 into the box 100.-

In the precedin description certain apparatus has been escribed for carrying out our invention, but it will be evident that different mechanical equivalents may be used without departing from the spirit of our invention. iWhile we have described the paste sprayer as using flour paste and air with a certain type of sprayer, it is not essential to use these two materials or to mix the materials in the particular manner described, as the paste may be atomized by steam or by mechanical means.

Having described our invention, what we claim is x 1'. In apparatus for coating dry cell linings, a movable conveyer, a sprayer for applying coating material to the linings means for retaining a stack of linin s, a
